The opts argument can contain one or more of the options shown below.

convention =  Unadjusted, Preceding, ModifiedPreceding, Following, ModifiedFollowing, or MonthEndReference -- Provide business day conventions; default value is Following.

output = data or formatted -- Specify the type of output the AdjustDate command should return. If this option is set to data (default) the record containing the data information is returned. Otherwise the data is formatted using the format deduced from the original date.

The AdjustDate function adjusts a non-business day to the appropriate near business day with respect to the given convention.

The parameter date must be a date specified in any of the formats recognized by the ParseDate command.

The parameter calendar must be either a name representing a supported calendar (e.g. Toronto, NewYork) or a calendar data structure created using the Calendar constructor.

Business day (date rolling) convention specifies the algorithm used to adjust a date in case it is not a valid business day. Here are the business day conventions supported by the package.
